SPECIFIATIONformng part of Letters Patent No. 714,956, dated December 2, 1902.

Application tiled September 6, 1902. Serial No. 122,396. (No model.)

T0 @ZZ whom, t may concern:

Be it known that I, CHARLES P. SIMMONS, a citizen of the United States, residing at Baltimore, in the State of Maryland,have invented certain new and useful Improvements in Filters, of which the following is a specification.

This invention relates to water-filters in which two iiltering-chambers are employed; and the object of the invention is to provide a system of pipe connections between the two chambers and the inlet for the unfiltered water and the outlet for the filtered water and to provide such connections with valves and mechanism to operate a plurality of such valves simultaneously for the purpose of dividing and directing the flow of the incoming current of water in different directions, as may be desired.

The invention will be fully described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is an elevation, partly broken away, of a filter constructedin accordance with my invention. Figs. 2 and 3 are vertical sections taken on the line a: a@ of Fig. 1, showing the valves in dilerent positions.

The iilteringchambers are indicated by A A' and are substantial duplicates of each other.

B indicates a valve-casing provided with four threaded nipples, (indicated, respectively, by Z), b', b2, and 53,) the first two being opposite each other in a horizontal plane. A pipe 10 extends from the nipple b into the upper end of the chamber A, and a similar pipe 11 extends from the nipple b into the upper end of the chamber A', and the extensions, as 10, of these pipes 10 and 11 within the chambers are preferably perforated, as shown in Fig. 1. The supply-pipe 12 is connected to the nipple b2, and a pipe 13 is connected to the nipple b3, for a purpose to be hereinafter explained.

The chambers A and Al are provided with discharge pipes d and d, respectively, at their lower ends, and these pipes are connected to a coupling D, which, in addition to the two threaded nipples to which the pipes d and d are connected, is provided with two threaded nipples d2 and d3, to the former of which the service-pipe 14 is connected,while the lower end of pipe 13 is connected to the nipple d?. Each pipe d d( is provided with a valve, (indicated, respectively, by e and e,) by means of which the flow of filtered water from the chambers may be cut off when desired.

Within the casing B is a hollow plug C,open at its inner end and provided with three lateral water-passages c, c', and c2, adapted to register with the nipples b, b', and b3, according to the position of the plug. The passages c and c' are opposite each other, and when the plug C is in the position shown in Fig. 2 the water from the supply-pipe 12 will enter the open end of the plug C, thence out through the passages c c into pipes 10 and 11, respectively, and into the chambers A and A, where it will be filtered and delivered through pipes d and d to the service-pipe 14, and this is the normal position of the parts.

The pipe 13 is provided with a valve f intermediate its ends, and near its lower end it is provided with a threaded nipple 18, to which is secured a valve-casing G, and this casing is provided with two nipples g g', opposite each other, and from these nipples pipes 19 and 20 respectively lead into the lower ends of the chambers A and A', and these pipes extend upwardly within the chambers to a point just below the surface of the filtering material in said chambers. The upper ends ofthe pipes 19 and 20 are closed, and each pipe is provided with a large number of radiating branoh pipes, (indicated by 21 in Fig. 1,) which branch pipes are of varying lengths and are bent up and left open at their outer ends, so that when water is supplied to the pipes 19 and 20 it will be discharged in a series of small jets from the pipes 21 throughout the body of the filtering material.

A hollow plug H is itted to turn in the casing G, and its inner end is open in order that water from the pipe 13 may enter it. The plug is provided with a water-passage 71 adapted to register with eitherof the nipples g g', but normally-thatis, when water is being iiltered in both chambers A A'this passage will be in the position indicated in Fig. 2, and no water can pass from the piper13 to either oi. the pipes 19 and 20. 1

From the upper ends ofthe chambers A A pipes 22 and 23 respectively lead to a valvecasing I, provided with a threaded nipple t', to

IOO

which a waste-pipe 24 may be connected. A hollow plug K is iitted to turn in the casing I and is provided with a water-passage 7a, adapted to register with either of the pipes 22 and 23. Normally, however, this passage occupies the position shown in Fig. 2 and will not register with either of said pipes.

Each of the plugs K, C, and I-I is provided at its outer end with a bevel-pinion, (indicated, respectively, by 25, 26, and 27.)

L indicates a vertical shaft supported to turn in bearings Z l, which are supported by the chambers A A', and to this shaft are adjustably secured bevel-pinions 28, 29, and 30, meshing, respectively, with the pinions 25, 26, and 27. The shaft L is provided with a lever or handle M, having a pointer m, projecting from the opposite side of the shaft.

It frequently becomes necessary to wash the filtering material in the chambers A and A', and such wash-ing must be conducted in one chamber at a time. 1f it is desired to wash the material in chamber A' and assuming the plugs K, C, and H to be in the positions indicated in Fig. 2 and that the valve f is closed, the lever M must be turned so the pointer 'm is toward the chamber A', and this will result in turning the plugs K, C, and H to the positions indicated in Fig. 3, and the passages 7c and h (indicated in dotted lines in said ligure) will be in communication with chamber A', while the passage c2 will be in communication with the chamber A and the passage c in communication with pipe 13, and there will be no communication between the supply-pipe 12 and the pipe 11. Water will then flow from the supply-pipe into the top of chamber A, be iiltered in its passage down through the chamber A, and pass through pipes d d' intothe bottom of chamber A', up through this latter chamber, out through the passage la to the Waste-pipe 24E, carrying with it impurities that may have lodged in the filtering material'. If now it is desirable to subject the filtering material to more vigorous washing, the valve f will be opened, and unfiltered water will pass from the supply-pipe 12 through passage c into pipe 13 and thence into .plug H and through passage h into pipe 20, from whence it will escape in a series of jets from the numerous small tubes similar to those indicated by 21 in Fig. 1, and this will have the effect of agitating the entire body of filtering material, and thereby greatly facilitate the washing of su ch material. The material in chamber A may be treated in the same manner by turning the lever M in the opposite direction.

Sometimes it may be desirable to supply unfiltered water to the service-pipe, and this may be accomplished by turning the plugs K, C, and H a half-revolution from their positions shown in Fig. 2, opening valve fand closing valves e and c', and then the only open passage from the supply-pipe to the servicepipe will be through the pipe 13.
